Charging the Lithium-Ion Battery Pack
Automatic shutdown of the HT650
The HT650 will enter idle mode when there is no task, or all tasks are waiting for input. In default
setting, the HT650 will automatically turn itself off if it remains idle for 3 minutes and when there
is no external charging power applied. Pressing the power button will return the HT650 to the
same point at the time of automatic shutdown.
Do not leave the terminal for a long time in the charging cradle and do not charge the battery
with a cable long, which will shorten the battery life and cause battery expanding/ballooning.
The unit should not be subject to very high temperature, excessive moisture, and direct heat.
Avoid the battery from being fully charged and staying in a high temperature environment. Avoid
terminal or spare battery from staying in a hot vehicle. For prolonging the storage time, keep the
battery at a 40% charge level. Lithium ion batteries oxidize least when they are stored at the
state of 40% charge.
To save the battery power, it is better to turn off wireless mode. Please follow the steps below to
turn off the wireless mode
